Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

For an 8.5 hour flight the service on board lacked a bit. Service start was slow, the food was worse than usual and they skipped the snack they were supposed to deliver before landing.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

DO NOT BOOK THROUGH AMERICAN AIRLINES IF YOU HAVE ANY ADDITIONAL NEEDS. Great flight, crew etc. it wasn’t full so had space to stretch out Only downside was there was no GF option for my partner. We booked through American and it was a Qantas flight so despite contacting both airlines to confirm, she didn’t have a gluten free meal for the 16 hour flight (nor the flight in the other direction). The flight attendants did their best to accommodate but it was not super substantial.

After several delays and being rebooked onto a layer flight, I had to speak to three AA agents for baggage claim to get an attendant. All were in foul mode and reluctant to assist or offer any assistance.

Multiple maintenance delays and the missed and rebooked connection changed gates at least 6 times including one which had us walking 20 minutes to another terminal and then back again. Seated our family of three in different middle seats throughout the plane and then there was an empty seat next to me. Very long travel day which I would have never agreed to if I knew the itinerary would be changed at 5 am, 2 hours before takeoff.

It was as expected for such a short flight. No complaints

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

Excellent crew, great food despite catering issues. We need more people like this.

1. The PA system was painfully loud. 2. Overhead bin #33 was missing—I find this troubling.

I had a disappointing experience at the San Diego airport with one of your gate agents. Despite being in Zone 4 and traveling with a standard carry-on bag that has never been an issue (30 flights in Q4 alone), the tall, blonde gentleman forced me to gate-check my bag. When I politely asked if we could verify the bag’s size, he became confrontational, even threatening to deny me boarding twice. His behavior appeared erratic and unprofessional, projecting a negative attitude onto passengers, as if he was going through something mentally. Notably, there was ample overhead space once all passengers had boarded. In contrast, the tall, older Asian agent handled the situation with professionalism and calmness, making a clear effort to de-escalate. As an avid traveler, this unnecessary inconvenience set a frustrating tone for my trip to Asia.

This leg was run by United. Food was ok and the regular menu was actually not good ( Hindu meal was fine). Crew was fantastic

Very unfriendly crew, Air Canada should hire staff that are willing to do their job and be friendly to others. Unmannered flight attendants.

The fact that we have to check in our carryons when we met the requirements and there was plenty of spaces near we sat was ridiculous

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

There was a terrible delay upon arrival in Barcelona. The plane had to park a great distance from the terminal, and only one bus was available to make the ~15 minutes each way trip, meaning it was ~ 45 minutes after we landed that I finally entered the terminal.

Hated charging my devices. The location of the outlet was inconvenient. And no USB connection. So outdated.

I was very good. Service was great. Seating selection was not too good.

Lufthansa charged me $280 to take skiiis when in the US the boot bag and skiis are one check-in bag. This was not advertised and a real shock at the airport. They only took the boot bag as a check-in item. The seats have been squeezed together like any economy airline and legroom is not as good as it used to be. Otherwise, the flight was fine and staff was helpful for making my connection.

Professional crew and staff, very organized boarding and on time flights, baggage handling. Indian vegetarian meals were good, though could improve by offering Indian bread (naan/paratha/roti) as well. Very helpful pre flight emails with details of onboard experience 👍 Above average selection of movies. Consider offering more movies with subtitles and ratings indicators (e.g., IMDB scores).

Terrible experience. Should be a short simple flight from San Francisco to Palm Springs. Disgusting insult that United Air doesn’t have a cabin crew ready to receive a plane that’s already an hour plus late in departure. Lots of misinformation along the way from cockpit and crew. Definitely unimpressed with both union and management.

My flight was delayed d the gate was never updated inside the terminal. If I hadn’t checked my email I would have missed my flight. Also, I paid a total of $5100 for my flight to be. Business or first class. My final leg of my flight from Heathrow to Frankfurt was not to standard of what I expected or experienced in the previous legs of my trip.

I requested a wheelchair for they haven’t got it, they are old and don’t speech english

The real bathroom smelled horrible and it smelled in the real of the plane..

Good but entertainment system was not easy and very buggy

They gave us free up grade to a roomier seat.

The connection between my income flight and the outgoing flight was slightly late and they would not hold the next flight for 7 minutes. The next flight was 4 hours later and we were issued a stand by ticket. So we had to wait to find out if we would even be on that flight. After boarding that flight was delayed for 40 minutes because there wasn’t a ground crew to load the luggage. The airline is not living up to it reputation.

The flight was cold, no enough blanket and the crew said that they can’t change it. I got very sick in the flight . Most of the kids were coughing.

The flight was okay, but legroom was tight for me and I’m only average height, although at 30” legroom is comparable with most other airlines. Not much room in the aisle either making the trek to and from the toilet difficult with passengers standing in the aisle. On the whole, it’s probably on a par with budget airlines and the ticket process extremely competitive.

Flight delay and can’t much help passenger do the change connecting flight.

The seats in airbus from LA to London are uncomfortable. They are too narrow. I am a slim person but felt cramped. The way the seats are laid out really hinders privacy. You are forced to look at the person next to you which is awkward, Also the entertainment on the same leg was limited. The crew was excellent and attentive and the food was decent. The seats on London to Delhi leg were way better. The crew again was very attentive and polite.

Reasonably comfortable. Plenty of room. Crew were attentive and continually informing passengers of position. Although stuck in runway for 1 hour, weather issues, it felt like we were the crews first priority

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

The whole experience was great. The only improvement would be the entertainment selection

It was good overall. Entertainment was ok, one of the TV screens had issue. Bit old plane but leg space was good. Overhead luggage had good space. The worst part was experience at Heathrow airport, it was total chaos.

Lost our luggage going to Spain. Missed our connecting flight returning to home

It would be great to have at least two choices for a food, instead of just plain pasta 😏

Cabin crew were not nice. The plane was an hour late arriving.
